Question:
A mate has a 3GS that came from AT&T and its on 4.1 and rooted and unlocked with Cydia.
Whats best option to get to 6.1 and unlocked.
Will he loose his settings and apps and unlock if he does and upgrade to 6.1 in iTunes and then run Evasi0n.
What app is needed to unlock once cydia is loaded.
Sorry for all the questions but Im not an apple user...
